Macro to Add Strong Names to VS.NET Projects


When writing class libraries in Visual Studio .NET that are going to be placed into the GAC you will need to add strong name to the assembly. This is normally done by dropping out to a dos prompt and running the .NET utility sn.exe and then updating the assembly to reference the newly created.snk file. This looked like a great place for a macro to be able to do this all within the IDE. Below is a macro that when run opens up a standard windows dialog box allowing you to navigate to the assembly you would like to add the strong name too. Next, the sn.exe utility will be run on this assembly and added to the current project in the IDE.

There are a couple of things to keep in mind when using this macro. First is that if you have a solution open with several projects in it make sure that the project that you want to add the snk file too has focus. Next, you are required to compile the project before using the macro do to the fact that you must navigate to the assembly in order to run sn.exe on it. Finally, the sn.exe utility is currently set to run with the -k option, if you want other options then you will need to change this.

To use this macro navigate to Tool/Macros/Macro IDE. Next, navigate to the File / Add New Item and choose a Module. Finally, take all the code listed below and paste it inside the newly create module and save the project. The macro should now show up in the Macro explorer and you should be able
to run it from right inside the IDE.
